What is the Klein 809-36MF — and why does a milled-face lineman's hammer dominate pole-line work?
The Klein Tools 809-36MF is a lineman's milled-face hammer: a heavy, double-faced hammer built for pole-line work. One face is milled (textured) for driving the staples used in pole-line work and common, unhardened nails, and the other face is smooth for driving heavier-duty hardware. A forged, tempered-steel head is only 3-3/4" long so it can be used in tight areas, and the 36 oz head has the weight to drive lag bolts.
Utility linemen and electrical contractors reach for it wherever staples, nails, and lag bolts need to be driven at height or in cramped spots. Klein's current catalog description adds a built-in J-hook remover (a 2-in-1 feature), an ergonomic handle, and an overstrike protection feature to improve durability. Klein also warns that both the user and bystanders should wear safety goggles. Note that some distributors describe the same part number with a fiberglass handle for impact absorption and without mentioning the J-hook remover, so confirm which version you are getting.
Common configuration: 14" overall length, 36 oz (2.25 lb, 1021 g) head weight, a head about 3.85" long made of forged 1055 steel, and a face of 1.375" x 1.5" (3.5 x 3.8 cm) per Klein's spec page, with the handle listed as polypropylene and TPR in black/orange (12.46" long). Weight is listed as about 2.5 lb at most distributors, while Klein's spec page lists 2.87 lb. The hammer is made in the USA, carries UPC 092644810008, and is also listed under the numbers 80936MF and 81000-8.
